Fluent Sentence UI: Render sentence, selects, and provider field dependencies #343
Description
Implement the frontend UI to render base sentence, required fields, and option selects using AutomationTemplate metadata and Provider Field Catalog.
- For a chosen AutomationTemplate, display the human-readable base sentence (e.g. "For each reservation in [workspace] on [board]...")
- Render required fields as selects populated from Provider Field Catalog/option sources (M2 API)
- Enforce dependency chains (e.g. workspace → board → list)
- Validations: user cannot proceed unless all required fields selected (template-driven)
Exit criteria:
- Fluent sentence UI built for Trello Cleaning/Spot-Check templates
- Selects render with live data from the options API
- Field dependency and validation logic complete
- Demo: user chooses a template and is guided through required field selection until all dependent fields are set
